Design considerations for a 5G network architecture
TL;DR: A two-layer architecture is proposed, consisting of a radio network and a network cloud, integrating various enablers such as small cells, massive MIMO, control/user plane split, NFV, and SDN, to address the challenges placed on 5G mobile networks.
EU FP7 INFSO-ICT-317669 METIS, D1.1 Scenarios, requirements and KPIs for 5G mobile and wireless system

TL;DR: The deliverable will not only serve as the guideline for the technical work and system concept design in METIS, but also can serve in external research communities to help to harmonize the work towards the future radio access system including the new generation system of 5G.
Proceedings ArticleDOI
5G service requirements and operational use cases: Analysis and METIS II vision
Salah Eddine Elayoubi,Mikael Fallgren,Panagiotis Spapis,Gerd Zimmermann,David Martin-Sacristan,Changqing Yang,Sebastien Jeux,Patrick Agyapong,Luis M. Campoy,Yinan Qi,Shubhranshu Singh +10 more
TL;DR: The landscape of 5G use cases is analyzed and METIS-II 5GUse cases that cover the main 5G services, have stringent requirements and whose technical solutions are expected to serve other similar use cases as well are presented.
Proceedings ArticleDOI
Database-aided energy savings in next generation dual connectivity heterogeneous networks
TL;DR: A novel database-aided mechanism is introduced to provide macro cell-controlled sleep mode functionality to small cells to yield energy savings and throughput gains in dense deployment scenarios compared to a system where no energy savings scheme is implemented.
Patent
Macro-cell assisted small cell discovery and resource activation
TL;DR: In this article, a method for controlling a small cell base station and a user equipment to be served by the small base station in a wireless communication system having a plurality of small-cell base stations controlled by a macro base station is described.
